2017-04-10make test: automatic "vpp finishes startup" checkKlement Sekera3-13/+59
Add code which checks if vpp doesn't crash/exit immediately after startup to aid debugging stuff like mistyped graph node name or so. Refuse to run tests if the vpp is unable to start, complain loudly and print vpp's stderr at critical log level if this happens to make spotting these problems in jenkins easy.

2017-04-07MPLS McastNeale Ranns5-27/+351
1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

2017-04-06acl-plugin: make the IPv4/IPv6 non-first fragment handling in line with ACL ↵Andrew Yourtchenko2-9/+91
(VPP-682) This fixes the previously-implicit "drop all non-first fragments" behavior to be more in line with security rules: a non-first fragment is treated for the purposes of matching the ACL as a packet with the port match succeeding. This allows to change the behavior to permit the fragmented packets for the default "permit specific rules" ruleset, but also gives the flexibility to block the non-initial fragments by inserting into the begining a bogus rule which would deny the L4 traffic. Also, add a knob which allows to potentially turn this behavior off in case of a dire need (and revert to dropping all non-initial fragments), via a debug CLI.

2017-04-06BFD-FIB interactionsNeale Ranns3-4/+107
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

2017-04-05GRE over IPv6Ciara Loftus2-7/+177
Refactors the GRE node to work with both IPv4 and IPv6 transports. Note that this changes the binary configuration API to support both address families; each address uses the same memory for either address type and a flag to indicate which is in use. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create gre tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 CLI: create gre tunnel src 2620:124:9000::1 dst 2620:124:9000::2 IPv4 VAT: gre_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 VAT: gre_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 Change-Id: Ica8ee775dc101047fb8cd41617ddc8fafc2741b0 Signed-off-by: Ciara Loftus <ciara.loftus@intel.com>
2017-04-03make test: relax BFD time intervalsKlement Sekera2-8/+10
Increased time intervals mean longer test runs, but also reduce the chance of getting annoying (especially in gerrit) random failures. Now that tests are split into `basic' and `all', the increased runtime of BFD tests (of which majority doesn't run in basic case) doesn't matter too much..

Allows easy running of test(s) in a loop with configurable action (e.g. git pull) run between test runs and possible email notification on failure. Usage: test-loop.sh [-p <pre-exec-cmd>] [-m <email>] -- <make test options> Example: Run 'make test-debug' in a loop until a failure is encountered, upon which an email is fired to ksekera@cisco.com. In between test runs, update the workspace using via 'git pull' and if anything changed, perform 'git clean' before running another 'make test-debug': test/scripts/test-loop.sh -p test/scripts/git_pull_or_clean.sh \ -m ksekera@cisco.com -- test-debug Change-Id: I114321c6c152d2c7e181e915fc8c51aab1ff3693 Signed-off-by: Klement Sekera <ksekera@cisco.com>
